Imeko yesicelo ye-seluplose ether

I-SelerUlose Ether yi-polymer ye-ionic ye-unic ye-unic ye-unic ye-unic ye-unic ye-unic ye-unic ye-semi-inyibilikisi kwaye inyibilikiswe ngamanzi. Ineziphumo ezahlukeneyo kumashishini ahlukeneyo. Umzekelo, kwizinto zokwakha iikhemikhali, ineziphumo ezihlanganisiweyo zilandelayo:
I-①water igcina iarhente yearhente ②thickener
Kwishishini le-polyvinyl pherviny, sisimo esouressifier kwaye sisasazeke; Kumzi-mveliso wamachiza, yindawo yokubhabha kunye ne-Spof Stores, ilawulwa, njl njl. Oku kulandelayo kugxilwe kusetyenziso kunye nomsebenzi we-seluplose ither kwizinto ezahlukeneyo zokwakha.
(1) kwipeyinti ye-Latex:
I.ADD ngqo kwimveliso: Le ndlela kufuneka inyule i-hydroxythl seluplose yohlobo oluthile, kunye ne-hydroxytethl seluplose enexesha lokuchithwa kwemizuzu engama-30, amanyathelo ayo asebenzisayo ngolu hlobo lulandelayo:
① Beka inani elithile lamanzi acocekileyo kwisitya esixhotywe ngumxube we-Shear ophakamileyo
②Start ukufunxa uqhubeka ngesantya esisezantsi, kwaye kwangaxeshanye kancinci uyongeza i-hydroxyytethl kwisisombululo ngokulinganayo
③continunue ukudibanisa kude kube zonke iigram zifakwe
I-④ADD enye yongezwa kunye neziseko zezongezo, njl.
I-⑤stir ide ichithwe yonke i-hydroxyly, yongeza amanye amacandelo kwifomula, kunye nokugaya kude kube yimveliso egqityiweyo.
Ⅱ. Ixhotywe ngotywala bukamama ukuba isetyenziswe kamva: Le ndlela inokukhetha i-seluplose yethutyana, enefuthe lokuphononongwa. Inzuzo yale ndlela kukuba iguquguqukele ngakumbi kwaye inokutongelwa ngokuthe ngqo kwipeyinti ye-Latex. Indlela yokulungiselela iyafana namanyathelo ①-④.
Ⅲ. Lungiselela i-Porridge yokusetyenziswa kamva: Ekubeni izinyibilikisi zendalo zizinto ezinqabileyo (i-insullen) ye-hydroxyyteythl, ezi zinyibilikisi zinokusetyenziselwa ukulungisa i-porridge. Ezona zigqibo zisetyenziswayo zisetyenziswayo zisetyenziswayo zizinto eziphilayo ze-organic kwindawo yokupeyinta i-FEELX, ezinje nge-ithylene glycol, i-propylene glycol, kunye neearhente zefilimu (ezinjengee-dizylene glyl suttate). I-Porridge ye-Holdroxythyl isellise inokulongezwa ngokuthe ngqo kwipeyinti. Qhubeka nokuvuselela kude kukhanyeswe ngokupheleleyo.
(2) Kwi-Dolop Skutty:
Okwangoku, kwizixeko ezininzi kwilizwe lam, indawo yokunganyangekiyo kunye nokunganyangeki kwendawo enganyangekiyo ixabiswe ngabantu. Iveliswa yimpendulo ye-acetal ye-vinyl utywala kunye ne-formaldehydehyde. Ke ngoko, le nto ishenxiswa ngabantu, kwaye i-Sersuse Ether Erise Series isetyenziselwa ukutshintsha olu phawu. Oko kukuthi, ukuphuculwa kwezinto zokwakha ezinobuhlobo bokusingqongileyo, i-sellyuese okwangoku kuphela kwezinto.
Ngenxa ye-viscosity ephezulu yeselselose, i-Buoyisay ye-ITTY iphuculwe, kwaye i-Shenomen etyhafileyo iphinde yathintelwa, kwaye ikhululekile kakhulu kwaye ikhuselekile ekusebenzeni. Kulungele ukongeza i-seluplose ether kwi-powder itoty. Ukuveliswa kwayo kunye nokusetyenziswa kwayo kulula ngakumbi. I-fililler kunye nezongezo zinokudityaniswa ngokucacileyo kwi-powder eyomileyo.
(3) Umlanjana wekhonkrithi:
Ngombutho wekhonkrithi, ukufezekisa amandla okugqibela, isamente kufuneka ihluleke ngokupheleleyo. Ngakumbi ukwakhiwa kwehlobo, udaka lwekhonkrithi luphulukana namanzi ngokukhawuleza, kwaye amanyathelo o-hydration ogqityiweyo asetyenziselwa ukugcina nokutshiza amanzi. Inkunkuma yezixhobo kunye nokusebenza okungahambelaniyo. Isitshixo kukuba amanzi aphezulu, kwaye i-hydration yangaphakathi ingaphelelanga. Ke ngoko, isisombululo sale ngxaki kukudibanisa ii-arhente zokugcina amanzi asibhozo kwikhonkrithi. Ngokubanzi, i-hydroxyl ye-hythyl okanye i-methyl seluplose, i-viscofity ye-viscosity iphakathi kuka-20000-60000c, kunye nexabiso elongeziweyo yi-2% -3%. Ireyithi yokugcina amanzi inokunyuswa ngaphezulu kwe-85%. Indlela yokusetyenziswa kwikhonkrithi yekhonkrithi kukudibanisa umgubo owomileyo ngokulinganayo kwaye uthule emanzini.

Ngophuhliso olukhawulezileyo lweshishini lokwakha, imfuno yabantu yezinto zokwakha ezitsha ikwanda imihla ngemihla. Ngenxa yokwanda kokwaziswa kwabantu kukhuseleko lwendalo kunye nokuphuculwa okuqhubekayo kokusebenza ngokukuko, iimveliso ze-cemestigual ze-cemestigual ziye zaphuhliswa ngokukhawuleza. Okwangoku, ezona ntlobo ziqhelekileyo ze-gypsum zifihla i-gypsum, i-godpsum ye-godpsum, i-insiid gypsum, kunye ne-tile. Ukupaka i-gypsum yinto ephakathi yokubekwa phantsi kweendonga zangaphakathi kunye nophahla. Umphezulu wodonga uphakanyisiwe kwaye kulungile kwaye kulungile. Ibhodi entsha yokwakha iBhodi yeBhodi yeBhodi ye-Adhengive yindawo enamathele e-Gypsim njengezixhobo ezisisiseko kunye nezixhobo ezahlukeneyo. Ilungele ukoyikwa phakathi kwezinto ezahlukeneyo zodonga. Ayisiyo inetyhefu, amandla e-odor, kwangoko kunye nokumiswa ngokukhawuleza, ukuxhobisa okuqinileyo kunye nezinye iimpawu, zizinto ezixhasayo zokwakha iibhodi zebhlokhi kunye nokwakhiwa kwebhloko; Iarhente ye-Gyppum ye-Gyppum ngumzili we-filler filler phakathi kweebhodi ze-gypsim kunye nokulungisa i-filler yedonga kunye neendonga.
Ezi mveliso ze-gypsim zinothotho lwemisebenzi eyahlukeneyo. Ukongeza kwindima ye-gypsim kunye neefilimu ezinxulumene noko, umba ophambili kukuba i-Seatheritives eyongezelelweyo idlala indima ekhokelayo. Kuba i-gypsum yahlulwe yaba yi-anhydaral gypsum kwaye i-hemimdrate gypsum, i-gypsum eyahlukileyo ineziphumo ezahlukeneyo kwimveliso, i-curing, ukugcinwa kwamanzi, ukugcinwa kwamanzi kunye nokubuyiselwa komhlaba. Ingxaki eqhelekileyo yezi zixhobo ikhutshiwe kwaye ikhwele, kwaye amandla okuqala akanakufikelelwa. Ukusombulula le ngxaki, kukukhetha uhlobo lwesellulose kunye nendlela yokusetyenziswa kwesixhobo sokuhlala. Kule meko, i-methyl okanye i-hydroxypropyl methyl i-30000 inyuliwe. -600cpps, isixa esongeziweyo siphakathi kwe-1.5% ne-2%, kwaye ugxininiso lwe-seluplose kukugcinwa kwamanzi kunye nokubuyisa i-conbrication yamanzi kunye nokubuyisa i-conbrication yamanzi. Nangona kunjalo, akunakwenzeka ukuba ixhomekeke kwi-ether sether njenge-restarder, kwaye kuyanyanzeleka ukongeza i-cicric rearder ukuxuba kunye nokusetyenziswa ngaphandle kokuchaphazela amandla okuqala.
Ukugcinwa kwamanzi ngokubanzi kubhekisa ukuba amanzi amaninzi azakulahleka ngokwemvelo ngaphandle kokufunxa kwamanzi angaphandle. Ukuba udonga luyomile kakhulu, ukufunxa kwamanzi kunye nokuphuma kwendalo kumphezulu wendalo kuya kwenza ukuba izinto ziphulukane namanzi ngokukhawuleza, kwaye ukuqhekeza kwaye ukonakala kwaye kuyakwenzeka. Le ndlela yokusetyenziswa ixutywe nomgubo owomileyo. Ukuba ulungiselela isisombululo, nceda ujonge kwindlela yokulungiselela yesisombululo.
(5) uHlobo lweThermal
UHlolo lwe-insurser luhlobo olutsha lwezinto ezingaphakathi zokuThintelwa kwingingqi esemantla. Yinto eyenziwe ngodonga olwenziwe sisixhobo sokufakwa, udaka kunye ne-binder. Kule nto, i-seluplose idlala indima ephambili ekwenzeni nasekukhuliseni amandla. Ngokuqhelekileyo ukukhetha i-methyl seluplose nge-viscofity ephezulu (malunga ne-10000s), idosi ngokubanzi iphakathi kwe-2% -3%, kunye nendlela yokusetyenziswa komgubo owomileyo.
(6) Iarhente ye-interface
Khetha i-HPMC 20000cps ye-arhente ye-defament, khetha i-60000cps okanye ngaphezulu kwi-tile ye-tile, kwaye ugxile kwiarhente yokuthambisa kwi-arhente yolwaziso, enokuphucula amandla e-thennel kunye ne-anti-utolo. Isetyenziswe njengearhente yokugcina amanzi kwi-thayile yokuthintela iithayile kwi-diledy ngokukhawuleza kwaye iwele.
